Frequently Asked Questions
What is the maximum clock speed of PIC14000-04/SO and how does it affect real-time control tasks?
The PIC14000-04/SO runs at a maximum of 4 MHz, executing approximately 1 MIPS for simple PIC instruction cycles. While modest by modern standards, this clock rate is sufficient for timer-based control loops, ADC sampling, and serial communication at baud rates up to 9600 bps in legacy embedded applications.
Does PIC14000-04/SO include an ADC, and what analog measurement scenarios does that support?
Yes, the PIC14000-04/SO integrates an on-chip ADC enabling direct measurement of analog sensor outputs such as temperature sensors, potentiometers, and voltage dividers. This eliminates the need for an external ADC chip in battery monitoring, thermostat control, and industrial sensing designs using the 28-pin SOIC package.
How does the 28-pin SOIC package of PIC14000-04/SO support board-level integration in legacy systems?
The standard 28-pin SOIC package with 1.27 mm pin pitch is compatible with most PCB footprints designed for wide-body SOIC devices. It provides sufficient GPIO and peripheral pins to interface sensors, relays, and displays, making it a practical replacement component in existing industrial and consumer boards designed around the PIC14 architecture.
For procurement of legacy designs, what is the typical factory lead time and compliance status of PIC14000-04/SO?
Microchip lists a factory lead time of approximately 11 weeks for PIC14000-04/SO with RoHS and lead-free (Pb-free) compliance. Despite its 1995 introduction date, the device remains in production for maintenance of legacy systems where a 4 MHz, 28-pin SOIC PIC14 MCU with ADC is required.
